Solution

(d) In five kingdom classification of Whittaker, non-cellular organisms like viruses and viroids are not mentioned. Viruses did not find a place in classification since they are not truly 'living' and hence, they are considered as non-cellular.

Monera includes all unicellular prokaryotes called bacteria in which viruses can not be included

Protista includes all eukaryotic unicellular plant and animals fungi are heterotrophic /parasitic, cellular organism devoid of chlorophyll.
